IBM Compatible VGA Controller was introduced in April
of 1987. It was a logical extension to the CGA and EGA
graphics controllers introduced by IBM with the IBM PC/XT/AT
series of products. The controller itself is basic in
function, providing text or graphics at up to 640x480 and
256 colors. The implementation is another story altogether.
However, in most systems available today, VGA is still
required for boot sequencing, BIOS settings and error
handling. Although by comparison to a complete accelerated
system, small, it is critical to a fully PC compatible
graphics subsystem.
Silicon Spectrum offers an in house designed VGA core
which is fully IBM VGA compatible and fully tested with
Displaymate and real world functional tests. Silicon
Spectrum offers a PC compatible BIOS to ensure plug in
interoperability.
VGA is fully supported on every PC operating system with
no driver required. Our VGA IP includes:
- Host Interface (PCI or PCIe)
- 32 bit (64 optional) DDR2 memory controller at up to
200Mhz
- CRT controller
- VGA controller
